Episode notes
Broker That Feels Like A Tech Company
- Interactive Brokers (IBKR) combines global market access with industry-low trading costs for sophisticated traders.
- Its account growth and margins make it resemble a scalable technology or SaaS business more than a commodity broker.
Use Personal Experience As Research Starting Point
- Consider using products you personally rely on as research leads, but always verify before investing.
- Clay used his own switch to IBKR as a research starting point, then dug deeper before buying shares.
Margin Levels That Surprise
- IBKR posts extraordinary margins: ~82% gross and ~75% pre-tax, rivaling Visa and Meta.
- Those margins reflect heavy automation and fixed-cost leverage across growing account volumes.
